Formation of Novel Tetradentate Phosphine Ligand o-C6H4(PPhCH2CH2PPh2)2 by Coupling of Two Diphosphine Ligands Bound to Low-Valent Mo or W Center. Synthesis and Structure of [M{o-C6H4(PPhCH2CH2PPh2)2}(Ph2PCH2CH2PPh2)], (M = Mo, W)

We performed ab initio molecular orbital calculations to derive rate expressions for the reactions of N2O with O(3P) and CO. Major products of the O(3P) + N2O reactions are predicted to be NO + NO. Comparisons of calculated and experimental rate constants indicate good agreement exists with the most recent experimental values.
